Lette/rs Patent No. 92,474, dated July 13, 1869.

IMPROVED HORSE-POWER,

The Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom it may concern Bc it known that we, CYRUs ROBERTS and J cnnA. THROP, of Three Riversin the county of St. Joseph, and State ofMichigan, have invented certain new and useful Improvements inHorse-Powers, of lwhich the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, whichmake part of this specitication, and in which- Figure l represents aplan or top view of a horsepower embracing our improvements, when stakedin position for operation, and

Figure 2, a vertical longitudinal section of the same, at the line :u a:of fig. 1.

Our improvements are shown as applied to a mounted horse-power, or onewhich is placed upon wheels for convenience of transportation, but areequally applicable to a down power, the objects of our invention beingaccomplished in either class of machines, when in operation. 5

The improvements claimed under this patent consist- First, in aline-shaft, extending outward at the rear of the machine, and connected,hy a flexible coupling, with 'a tumbling-rod, mounted upon aframe hingedthereto, in such manner that the angle of the tumbling-rod with theline-shaft may be varied at pleasure, to answer the requirements of thework; and when not in operation, the frame maybe turned up, and used asa rack for supporting the levers, braces, 85C., of the horsepower, whilebeing transported. Second,"iu the employment of diagonal braces, rml yconnecting the bed-plate to the frame, the same being arranged iu thedirection of the lstrain to which the former is subjected by the pull ofthe horses when operating the power, and serving to obviate liability ofits working loose or becoming disconnected.

o rl`hird, in au improved method'ofstaking the machine to the gro -whenin operation, whereby both lateral and end-. i of the same areprevented,and the power of the"'h"orses effectively exerted, withoutrisk of altering its position, as hereinafter more fully set forth.

In the accompanying drawings, which show a con-I venient arrangement ot'parts for carrying out the objects of our invention, A represents theframe of lthe machine, which, for strength, and convenience ofconstruction and-operation, is made in angular form, being narrowest atits front end. l

The frame A is supported upon the front and rear Aaxles B B1, whichcarry wheels B2, the front axle being pivoted to the frame by aking-bolt, b, so as to be turned in either direction while the machineis being moved from place to place.

The gearing oy which the'line-shaft is rotated is mounted in andsupported by 'an annular metallic bedplate, O, which is firmly bolted toside sills or beams a, upon the frame. l

The bevel-wheel, which gears with the pinion upon the line-shaft, isalone represented, the remainder of the gearing, and the levers to whichthe horses are attached, not being compreheuded in the improvementsherein claimed, and being liable to be differently constructed indifferent machines.

D represents the line-shaft, the front end of which is supported in abearing, el, pivoted to a hanger, C, formed in a piece with or securedto the lower side of the-bed-plate. This shaft extends outward at therear of the machine,and may be sct at any angle desired, its rear end Ybeing supported in a bearing within, above, or below the axle B1, asfound most convenient.

In addition to being bolted to the frame, as before stated, thebed-plate C is further secured thereto by diagonal braces G2, arrangedin the line of the strain exerted by the horses when operating thehorse-power, they travelling in the direction of the arrows in fig. l.The braces C2 connect the bed-plate and frame rigidly 1 together, andeffectually prevent the former from being loosened or displaced.

An angular frame, E, provided with a transverse bolster, El, is hingedto the rear of the machine, and may 'be turned up perpendicnlarlythereto, or set at any desired angle, its free end resting upon theground or on a block of suitable height.

The frame E carries the tumbling-rod F, which is connected to a pivotedor flexible coupling, ll', upon the end of the line-shaft D, and has itsrear end supported by the frame. The tumbling-rodis coupled to the shaftof the machinery to be driven, and, by means of the hinged frame andpivoted coupling described, can be readily adj usted to the heightthereof, without altering the level of the bed-plate and frame A.

In order to maintain our horse-power ir'mly in position upon the ground,when ready for operation, and prevent it from being displaced by themovements vof the horses, the following devices are employed:

Sockets lt h1 are secured to the sides of the frame, contiguous to thefront and rear axles respectively.

Braces or beams H are inserted in the sockets, having their oppositeends resting upon the ground, andy extending'in the direction oi'the'movemeut of the horses, as shown by the arrows, iig. 1.

Stakes l1,2 are irmly driven into the ground, againstl which the bracesH bear whenthe strain of the horses is brought upon them.

Rods H1 are hooked to rings or staples upon the frame, and extending inopposite direction -to the braces, are connected, by chains-H2, passingaround pins or rollers h thereon, to stakes h4, driven into the groundon opposite sides to the stakes h2.

By this arrangement, the four corners of thefranie are securely held,the tendency of the movements'of the horses being to push against 'thestakes hfiand pull upon stakes h*,while, by the relative positions ofthe braces, an effectual resistance is opposed to the displacement ofthe machine. l

Our improvements are free from complication, may be cheaply constructed,and when iu use, are found to accomplish, in a practical and effectivemanner, the objects of our invention. lVhat we cla-im as new, and desireto secure by Let-v ters Patent,is i

1. A line-shaft, extending outward at the rear of a horse-power,supported in a box or bearing below the bed-plate, and a bearing on therear axle, substantially as described, and for the purpose of enablingthe shaft' to be hung at any desired angle, as set forth.

2. A. hinged rear frame, :arryingr a tumbling-rod,

connected with the. line-shaft by a. pivoted coupling,
